Web applications design methodologies hold the promise of engineering high-quality and long-lived Web systems and rich Internet applications. However, many such methodologies focus solely on green-field development, and do not properly address the situation of leveraging the value locked in legacy systems. This paper proposes a holistic approach to redesigning legacy applications for the Web using the Ubiquitous Web Applications Design Framework (UWA) and an extended version of its Transaction Design Model (UWAT+). The approach blends design recovery technologies for capturing the know-how embedded in the legacy application with forward design methods particularly well suited for Web-based systems.
